How does body motion control occur? For example, walking on high heels during a strong wind is pretty hard. There is a compressible fluid flow across the body, the center of mass is changing all the time, you have to balance on a tiny surface area, sensor data from the skin, eyes, ears, etc. running into the Gb/s has to be integrated to motor controls... just thinking about it makes it seem complicated. Is the brain actually doing triple integrals and solving PDEs behind the scenes, or does it have a huge list of control signals to use in case of whatever inputs, or what?
